I do prefer Zoro, voted for him, and I do defend him on power level threads, but I do like Sanji quite a lot in his own right. Used to have figurines of both back when I was a teenager.
This is pretty much a Marvel vs DC topic. But worse, because Marvel vs DC is purely subjective, but Zoro vs Sanji devolves into power levels, which is more objective in this particular case, but then I'm supposed to be a hater just because I don't think Sanji is stronger (or truly as strong as) Zoro. I guess I can't like a character without wanking him to high heaven.
